Question

Show transcribed image textConsider the circuit of Figure 4. Assume that VDD= 10 V, Is = 2 mA. the NMOS transistor has Vt = 1 V, Kn = mu W/L=1 mA/V2 and the Early voltage VA=100 V. We assume that all the capacitances are perfect (act as short-circuits for the considered frequencies). With RG = 2 M Ohm and RD = 2.5 k Ohm, calculate the DC currents and voltages of the transistor. Find the voltage gain of the circuit. What is the purpose of the capacitance Cs? Figure 4
